Position of a point at circumference with respect to centre of a circle

A circle of radius a has charge density given by lambda=lambda_(0)cos^(2)theta on its circumference, where lambda_(0) is a positive constant and theta is the angular position of a point on the circle with respect to some reference line. The potential at the centre of the circle is

A,B,C and D are 4 points on the circumference of the circle and O is the centre of circle angle OBD - angle CBD = angle BDC - angle ODB find angle A

A disc is rolling without sliding on a horizontal surface. Velocity of the centre of the disc is V . Then the maximum relative sped of any point on the circumference of the disc with respect to point P is.
